IMPROVED SODA-.WATEFt APPARATUS.

Specification forming part of Letters Patent No. 40,347 dated October 20, 1863.

Tooll whom it may con'ccwn.v

Be it known that I, JOHN D; LYNDE, of

Philadelphia, in thelcounty of Philadelphia and State of Pennsylvania, have invented a new and useful Iin'provementin Soda-Water Apparatus; and I do hereby declare thatthe following is a full, clear, and exact description of the construction and operation of the same,

reference being had to the annexed drawings, making a part of this specification, in which- Figure is a perspective view; Figs.'2, 3,

and 4, transverse'seotions of parts Fig. 5, a.

top view of apart with a portion removed, and Fig. 6 a view of a part inverted. Fig. 7 is also a perspective view of a part;

In Fig. 1, A is a fountain in common use;

.13, the measuring-chamber; G, the filling-cock,

and D the small fountain, of any required size, to be filled to a given 'eiite'fit" with aerated water from A.

' Fig. 2 shows the construction. of the smallfountain D. a, the lining, is of glass, earthen-' ware, or metal, or any suitable material, provided with a Valve-faucet stopper, constructed as follows, of metal and rubber: bis-a mouthpiece screwed into the mouth or fixed tightly to the top of the fountain, making a tight joint by means of the packin go. Through b, in an easy hole, works the hollow valve-stem d, in

which the hole from the top connects with the cross-opening near its lower end. Just below and tapping this cross-opening is an annular depression sufficient to hold the rubber valv ing, Fig. 7; n e is a rubber spring, surroundingthe valvestem, serving to hold the valve closed and also as a packing when the fountain is being filled. When theparts of the stopper are in place, the opening in the bottom of b will be securely closed, the valve-rin g, Fig. 7, becoming a packing between thelower edge caused by the annular depression and the inner edge of lower end of b. The tube a, extending nearly to the bottom of the fountain, is connected to b by the thimble M, which is screwedonto the lower, end of b and incloses the valve in the chamber thus formed.

g is a metal case, a little largerthan the lining a. The interstice h is filled with'plasterof-paris or any substance which may be poured in and packed or hardened without shrinking from either vessel or be .afi'ected by temperature, sothat the strength of both a and 9 may be combined to'resist the pressure caused by the contents of a.

Figs. 3, 5, and 6 will explain the fillingcock 0.

Fig. 3 shows the channel It, through which the water and gas are passed. .11 is the airchan'ncl stopped by the screw-valve n; j, the rubber packing in the mouth-piece, to fit over the valve-stein d k, the channeled gate, held firmlyon its packed seat l by the screw m.

Fig. 5 is O with the gate K removed, which is shown inverted, Fi g. 6. It will be seen that water passing in through 0' would come up in hole 1). Now, if the gate K'is so placed as to 'br in g hole 5 over 1, thewater will pass through the channel in K and outihrou'gh holes etand 3. Then, by turning K so that 4 willbe over 2, a like connection will be madewith q,while tli e-"rorrner"e'omieenonw tspwn1 be closed."

Fig. 4 is a transverse section of the measuring-chamber B, which is constructed of any desirable material and supplied with three pipes, rs "6, two of which connect only with the top, while the other reaches nearly to the bottom. Water enters through '4" andpasses out through t. Gas passes out and in through 8. r is connected with the bottom of A, s with the top .of A, and t with thefiller G.

The operation is as follows: A isfilled two: thirds full of water, whichis thencharged with carbonic-acid gas,let in through the pipe u,of

the requisite pressure for workin g. Thecock 'v in pipe 1' is then opened and water passes from A and fills B. *1; is then closed. The

fountain 'I) to be filled is laid on the rack Z,'.

which is at' such an inclinationthatwhen D is three-fourths full the open end of pipe a will be above water. The filling-cock O is fastened firmly to .the lower end of the inclined- ;rack. D is then (slipped down the rack with the valve-stem d entersthe hole h, when it is. firmly held with sufiicient forceto close the joint tightly. This pressure will "then open the valve in-the stopper. The' gate Kis then set so as to connect holes 1 and 5*with4 and .3, when the water in .B will be forced by the gas in'A (coming through 8') through tand into the fountain' 'D. Closing the connection made byth'e gate, the air is let out of D' by opening the valve a, after which gas 'iS'tlfi-it into D by same pipe which brought the water As it is desirable that B should always be' filled at a uniform pressure, q is supplied with a pipe connecting with a fountain filled withgas at such a pressure as required, so that after the above-described operation the gate K may be turned to make a connection with q, when gas will flow into or out of D, as may be necessary from greater'or less press uie in A, thus securing a uniform pressurein D. The cap is then placed over the stopper to protect it dining transportation.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. The measuring-chamber B, the fountain D, and the improved valve f, all constructed ;and operated substantially as described.
